Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset limit switch (flame rollout switch) designed as a direct-fit replacement for the WFM18090S5CXCB gas furnace and compatible Goodman/Amana models. This normally-closed safety device opens the ignition circuit if it detects excessive heat from flame rollout — a critical protection against blocked heat exchangers or restricted venting. Because it is manual-reset, a tripped switch signals an underlying condition that should be inspected before pressing the reset button.

Specifications

Part number: 10123529
Type: Manual reset flame rollout limit switch
Configuration: Normally closed (opens on high temp)
Fits: Goodman WFM18090S5CXCB and compatible furnaces
Function: High-temperature safety shutoff

OEM vs. Generic

Our OEM Goodman switch is calibrated to the exact trip temperature the furnace was engineered around. Generic switches with mismatched setpoints can nuisance-trip or, worse, fail to trip — a genuine safety concern. Always use the correct OEM rating for combustion safety devices.

Installation Difficulty

Easy (1/5). Cut power and gas, disconnect the two spade terminals, unscrew the switch from the burner box, and mount the new 10123529 in the same location. Restore power and verify continuity. Investigate the root cause of any prior trip.
